Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-pump flexible tube systems struggle with precise control over the amount of substances squeezed out and often result in substances being sucked back into the tubes, leading to mixing issues.
Innovation Solution
A dual-pump outflowing liquid container design featuring an outer and inner tube with a pump core mechanism, including vacuum pumps and a pressing head, allows for simultaneous and controlled dispensing of two substances through intercommunicating holes and passages, ensuring precise rationing and preventing substance retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two flexible tubes are squeezed simultaneously to dispense two substances, then both substances can be dispensed at the same time, but it is difficult to control the amount of substances squeezed out and achieve precise rationing
Solution Approach 1:
The patent divides the single squeezing action into two independent pumping actions. Each substance has its own pump core (first pump core and second pump core) that can be independently actuated by separate pressing heads. This segmentation allows precise control over the amount of each substance dispensed while maintaining simultaneous dispensing capability, resolving the contradiction between productivity and measurement precision.
2Productivity
If two flexible tubes are squeezed simultaneously, then both substances can be dispensed, but when released the tube bodies recover automatically and suck back the substances, causing mixing of substances
Solution Approach 1:
The patent replaces the elastic recovery mechanism of flexible tubes with a positive displacement pumping mechanism. The pump cores with pressing heads provide unidirectional flow control through mechanical pumping action, eliminating the backward suction effect caused by elastic recovery. This substitution ensures that substances are dispensed forward without being sucked back, maintaining substance separation integrity while preserving dispensing efficiency.
3Device complexity
If a small flexible tube is sleeved in a big flexible tube with aligned outlets, then the structure is simple, but the operation is difficult to control and substances are sucked back
Solution Approach 1:
The patent segments the single integrated flexible tube structure into two separate tube-pump assemblies. Each assembly has its own pump core and pressing head, allowing independent operation. This segmentation transforms the difficult simultaneous squeezing operation into two independent, easily controlled pumping actions, significantly improving ease of operation and control precision while maintaining reasonable structural complexity.

Implementation Method 1
the pump core mechanism includes a pump core mounting seat, the first vacuum pump, the second vacuum pump and a pressing head
Implementation Method 2
when the two squeezed flexible tubes are released, tube bodies of the two flexible tubes can recover automatically under their elastic deformation and then suck back the substances squeezed out
